GE Dual Wave II microwave oven blowing fuse



Combo unit microwave over conventional oven with all controls on microwave. I think it's a 1990 vintage. Oven still works okay. Microwave with new fuse installed lights go on and it begins to start up and then blows the fuse again.

    I have GE Dual Wave II combo (Model: JKP6260K5). One week ago, I tried to head up the food and it started a few seconds and stopped. The light on the panel went out but the oven is still working. I am not sure if I can have it fixed. Or, I need to replace one.

    When does the fuse blow?

    Right after you press Start, a few seconds after you pres Start, or when it stops cooking?

    Please reply back with your model number, too, so we can help you.

It sounds like a shorted high voltage capacitor, a fairly cheap fix. But if it's good, I would suspect the high voltage transformer.

Here are some links you or a friend can use for test help, but read the safety warnings first:

There should be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

The fuse blows a couple of seconds after pressing Start, doesn't make it to the cooking stage. I've only attempted changing the fuse once as I am aware there is normally something causing it to blow. The model is JKP62GOK3 BG. I have seen references to the high voltage transformer possibly being the problem. Perhaps with the age of the unit it's just time to replace? Thanks, Gary

I have had this happen when either the control power supply, or the main high voltage power supply fails.

I do not suggest you try to service this yourself. There serious safety issues when servicing microwave ovens.

That's probably a shorted relay on the control circuit board.

We regularly repair such control units for customers nationwide by mail for $39.95 postpaid with a one-year guarantee.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

There is often a fuse and a magnetron thermal fuse or thermostat.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

I think I understand what you mean.

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers and Driver downloads as required.

Just Google the manufacturer's name and follow the links. Make certain you are directed to the manufacturer's web site as some search engines direct you to other sites and they charge for the information that is normally free of charge.


The magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.


I hope this helps.

Thats a defective product, and it should have just been replaced with a new one under warranty. Any device that is blowing out a recomended fuse rating frequently is defective. The product itself is overloading the fuse, and making it blowout. Do not under any circumstance replace it with a higher fuse rating. This will make the product a fire hazard. The technician should have looked into the problem which is not the fuse.

The micro wave part is not working in your oven. It is mainly due to to the defect in the magnetron and the related components like high voltage side fuse and high voltage diode etc. you can check the fuse and the diode with a multimeter. If they are ok replace the magnetron.

GE Dual Wave II microwave doesn't work, all power controls are out. Is there a user-replaceable fuse?


A microwave can be dead for many reasons.

It may be the fuse, which is usually located on the floor of the oven behind the control panel or between the door switches.

Ifthe fuse is good, it may be an open thermostat or thermal cutout (TCO)/ thermal fuse on or near the magnetron or on top of the cavity / bodyof the oven.

If it goes dead for a while during or after cookingthen comes back on, the magnetron is probably overheating and causingthe magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

Whenchecking thermostats, if it has a hood fan thermostat, that should readopen, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

Ifit goes dead or blows the breaker (or GFI) when you plug it in or open or closethe door, then there's a problem with a door switch or door switchmount.

If it's intermittent or random, it may be a badconnection, usually on the control board or a loose fuse holder, oreven an intermittent fuse.

You should do a continuity test onthe fuse while it's in the holder (with the microwave unplugged, ofcourse) then turn the fuse by hand or take it out and put it back in,then test it again.

If you remove the fuse, then press the meterleads against the ends, it can allow internal contact to be made andmake a bad fuse appear to be good.

If you or someone you knowdecide to look into it, we have critical safety information anddisassembly information at our site, and our link is at our listing here on FixYa.

Thereshould also be a "mini-manual" hidden inside the unit behind thecontrol panel or hidden on the left side behind the grille, which isvery helpful when troubleshooting & testing.
